NVIDIA Releases New Windows 7 Driver Set

With the "official" release of Windows 7 RC to the MSDN and TechNet subscribers today along with the public release scheduled for May 5th, NVIDIA released beta GPU driver set 185.81 today. The 32-bit driver set is available here and the 64-bit release is located here. Our first results this morning indicate this driver set is much more polished than the 181.71 release, along with several improvements in gaming performance and platform stability. NVIDIA also released the 185.81 driver set for the Vista and XP operating systems.
